Installing the Device4.1 Using Suction CupThe device is designed with a cupulate stand, and easily sucks to any smooth surface without making any damage. It is most suggested to place on glass surface for best and firmest suction result, or use the transparent self adhesive mylar provided in package if your counter top is not 100% smooth.To install the device, you need to:1. Clean the counter top and make sure the surface is smooth and dry.2. Adhesive the mylar on top of the counter (ignore this step if the counter top ismade with glass or very smooth).3. Attached the cupula in position, and press down the device to squeeze out theair in the suction cup. (shown in Figure 2)4. Press down the lever to secure device on the surface.(shown in Figure 3 step)5. Raise the lever to release the suction cup from the surface. (shown in Figure 3step )a. The mylar is 145mm in diameter self-adhesive for easyattachment, when stick onto surface, be careful andprevent bubble enters inside.b. The suction cup uses the vacuum theory to hold on to thesurface. If the surface is not smooth or cupulate isdamaged or dirty, air could go into the suction cup andthe cupulate will lost its function.Figure 2: Place cupula in positionand hold firmly with one hand.Figure 3: Press down lever tosecure device4.2 Using Mounting ScrewThe device is reserved with 3 mounting holes for permanent fixture if required. Refer to the figure below for detailed information.Unit: mm(inch)Figure 4: Mounting screw holes5. Adjusting Scan AngleThe device has a hinge shaft that allows tilt forwards and backwards in certain angle. Gently holds the device with one hand and move the scan angle as needed.Figure 5: Scan angleDo not let the scan beam facing directly to human eyes.6. Connection6.1 Interface CableThe interface cable comes with different host-end connectors, and there are 3 standard types of interface connection that this device supports:wedge(a) Keyboard(b) RS-232interface(c) HID USB interface**Refer to Connector and Pin our section for pin-out configuration of each interface availableInsert the cable to deviceFollow as illustrated in Figure 6 to insert the RJ-45 connector side of cable into the device. A clear “click” sound is heard if the cable is properly inserted.Figure 6: Interface cable connectionRelease the cable from deviceGently face down the device, and use a flat tool insert at Point 1 in Figure 7 then gently pull out the cable at the direction indicated at Point 2.6.2 Connecting to the HostFollow the steps below to connect the interface cable to the host.1. Make sure the power of the host system is off.2. Connect the host-end of the interface cable to the appropriate connector onthe host system.3. For those cases where external power is used, plug the external AC poweradapter into the jack on the interface cable.4. Turn on the host system.6.3 PowerConnectionThe scanner turns on when power is supplied, and turns off when power is removed. There is no on/off switch on the scanner itself.The scanner requires a minimum of 1.35W at 5 VDC power. The interface cable that comes with the scanner supports both direct power (where the scanner takes power from the host machine) and external power (that’s what the supplied power adapter is for). A sufficiently robust POS system can support a scanner successfully without external power; a POS system with a barely adequate power supply may produce erratic performance (either of the POS system itself, or of the scanner, or both) when a scanner is attached.To ensure steady performance, the host system should be capable to supply a ********************************************************** can handle such loading, it is recommended that you use the qualified power adapter. When an external adapter is connected, the scanner will automatically switch off the direct power from host to scanner.Use only an AC/DC power adapter approved for the scanner. Use ofother power supplies may cause damage to the scanner, and void thefactory warranty.Follow the steps below when you need an external power connection to the scanner:1. Connect the interface cable to the bottom of the scanner (shown inFigure 6).2. Connect the other end of the interface cable to the host (refer to yourhost manual to locate the correct port).6.4 Verifying Scanner OperationPlease follow the procedure below to verify scanning operation.1. Insert the modular plug of the Interface cable into the back of the scanneruntil a firm click is heard.2. If necessary, plug the power adapter into the jack on the interface cable.3. Plug the AC end of the power adapter into an AC outlet, or plug the other endof cable into host if power adapter is not needed. When power is supplied, the scanner powers up, the speaker sounds four beeps and the LED indicator glows.4. Present a known-good test barcode to the scanner. The scanner shouldissue a short beep and the LED should flash red momentarily.1. If the scanner is connected to a USB for this test, it shouldread one barcode, beep and then remain a red LED indicating light. This is normal when the USB is not connected to a live host terminal. If the initial interface of the scanner is in keyboard wedge, and it only reads one barcode and remains with a green LED indicating light, this is because the scanner is not connected to a host terminal.2. If the scanner does not produce any beeps, or producesthe wrong beeps, or the LED does not light up, remove the power connection and refer to the Troubleshooting section.7 Setting Up the ScannerIn certain cases no setup is required. The scanner is either pre-programmed to suit the situation, or it automatically detects and is ready to go. In other cases the scanner must be informed about what kind of system it is connected to. This can be done in a few moments using the programming barcodes in the Programming Guide.The programming section may be used to set a number of parameters on the scanner: communication interface type (RS-232, Keyboard, USB), beep tone, sleep mode timings, same-code delay time, enable/disable decoding of numerous code types, and more advanced settings like set headers and trailers. Individual parameters may be set at any time without affecting the other parameters.7.1 Scan Test1. With the scanner running (blue LED lights) and the host system on, try toscan several known-good barcodes.2. Check the results on the POS screen. If the scanner is reading okay, it islikely that no further setup is necessary.3. If the POS screen does not show the expected scans, go to the Set Upsection below.7.2 Set Up1. When the scanner is powered on (blue LED lights), find the <Enter/Exitprogramming mode> barcode in the Programming Guide and present this barcode to the scanner. When the scanner gives two beeps (one low and one high) and the LED turns red, it means the scanner is in programming mode.2. Decide which parameters are required and find their barcodes in theProgramming Guide.3. Cover unwanted codes with your hand and present the desired codes, oneby one, to the scanner; the scanner beeps once as it accepts each code.4. When done, again present the <Enter/Exit programming mode> barcode.The scanner beeps twice, once long and once short, and the LED returns to blue. The scanner has been programmed.5. Test again with known-good barcodes. If results are good, you are done8 How to Scan in Different ModeThe device is an omnidirectional presentation scanner with a 5 directional scan field with a 20 lines scan pattern. The scan volume extends approximately 20cm (8”) in front of the scan window. Barcode labels can be easily read when presented towards the scanning window. The scanner’s scan volume is illustrated as Figure 8.Figure 8: Scan volumeThe scanner can also read barcodes in single-line mode to accommodate different requirements, usually for better aiming on the specific barcode on the same sheet of more than one barcode printed closely.8.1 Presentation ModeIn this mode, the front scan window is in multi-line scan pattern and the scanner reads barcodes easily as the barcode approaches with the scanning field.Figure 9: Presentation modeThe adjustable stand allows to be tilted forwards and backwards in position when scanning various sized objects.8.2 Single Line Scan ModeIn this mode the scanner can emit a single line pattern for users to handheld scanning of hard-to-read or multiple barcodes on one object. Sales clerks can switch it to single line scan option simply by pressing one button.ButtonFigure 10: Single-line switch button1. Press down the trigger button and a line pattern would appear. It allows you toaim at the barcode.Ensure the scan line crosses every bar and space of the symbol.2.Press the button to decode the barcode. One beep indicates a good read.Figure 11: Single-line scanning3. Release the button and laser beam would remain single line for seconds. Toread other barcode, you have to repeat step 2 and 3.4. After about 5 seconds, the multi-line scan pattern is displayed and the scannerreturns to the multi line scan mode.5. Press down again to switch to single-line scan when necessary .9 Sleep ModeAfter the scanner has been inactive for a period of time, the laser and the motor would automatically turn off and the scanner would enter the sleep mode. The blue LED would blink as indication.It takes 2 steps to enter the sleep mode. The first step is the laser switching off after 10 minutes; the second step is the motor switching off after 30 minutes. The time period is programmable.To wake up the scanner, present an object close to the scan window, or press the trigger button.Figure 12: IR detecting rangeThe scanner includes a motion sensor that detects activity in front of thescan window. The detecting distance is about 10cm (3.9 inch)from thescan window w hile in condition with effectiveness of environment lights.The detecting distance is also programmable.10 LED IndicationsThere are red and blue dual color LED indications on the head of the device. They indicate the operational status of the scanner. The following are the LED statuses and their indications.Off No power supplied to the scanner.Steady blue light The scanner is on and ready to scan.One red flash A barcode has been successfully decoded.A barcode has been successfully decoded, but theobject is not removed from the scan window. Steady red lightThe scanner is in programming mode.Flashing blue light The scanner is in sleep mode.Steady purple light This indicates the scanner has a motor or laser failure. For motor failure, a periodic beep is sounded. In this case, return the unit for repair.Flashing red light The scanner is programmed in USB interface but not connected to a host device.11 Sound IndicationsThe device uses a speaker to give audible feedback on scanner operation. The following are the sound indications.One beep A barcode has been successfully decoded.Four beeps in series This indicates the scanner passed the power on self-test and is operating properly.Two beeps: low-high The scanner has entered programming mode.Two beeps: same tone Scanner has returned from programming to normal mode.Continuous tone This is a failure indication. Return the unit for repair.12 Controlling the Scanner from the POS SystemThe scanner can be controlled from the POS system via the RS-232C interface. Controlling can be accomplished by transmitting the following single byte commands to the scanner. The default settings of the commands are as follows:0E Hex enable (resumes disable) Shift Out or <Ctrl-N> 0F Hex disableShift In or <Ctrl-O> 05 Hex power-up re-initialization ENQ or <Ctrl-E> 12 Hex sleepDC2 <Ctrl-R>14 Hex wake up (resumes sleep) DC4 <Ctrl-T>When the scanner is disabled (unable to scan), the motor of the scanner will stay on until the scanner goes into sleep mode.13 USB Virtual COMSteps to Update Virtual COM Driver 1.
